CHARLES SEYMOUR, OF DEFIANOE, OHIO, ASSIGNOR TO THE DEFIANOE MAOHlNEWORKS, OF SAME PLACE.

MORTISING-MACHI NE.

SPECIFICATION forming part of Letters Patent No. 267,465, dated November14, 1882.

No model.)

To all whom it may concern:

Be it known that I, CHARLES SEYMOUR, of

Defiance, in the county of Defiance and State of Ohio, have invented newand useful Improvements in lVIortising-lVIachines; and I do herebydeclare that the following isa full,

clear, and exact description thereof, reference being had totheaccompanying drawing, which forms a part of this specification.

The nature of this invention relates to certain new and usefulimprovements in the construction of mortising-machines of that classdescribed in the patent to Charles 0. Strong, David B. Turnbull, andmyself, No. 239,881,

dated April 5, 1881; and theinvention consists in the combination,uponthe main drivingshaft of such machine,of asystem of frictional clutchesand pulleys, by means of which the operator is enabled to start and stopsimultaneously and promptly all the movements of such machine exceptthat of the boring-spindle, which, by a reverse movement of theclutchlever, is brought into action or released independently of theparts of the machine which govern the movements of the chisels, as

more fully hereinafter described.

In the accompanying drawing, which forms a part of this specification,the figure represents an elevation of my invention.

A represents the vertical frame which carries the working parts of themachine,-upon the top of which, and within the boxes at b, is journaledthe shaft B. Upon this shaft runs the loose pulley D, and sleeved uponthe shaft is a clutch provided with a pulley, O, and a friction-pulley,F.

r E is another frictional pulley,rigidly secured upon the shaft.

Gr is a lever by means of which the clutch is actuated, and when thefriction-pulley F is engaged with the pulley D a belt (not shown) fromsaid pulley gives motion to the boring apparatus below, and this motionwithdraws the pulley (J from contact with the rigid friction-pulley E. Areverse of this motion, dis- 5 engaging the friction-pulley F from theloose pulley D, stops the motion of the boring apparatus and brings thepulley G into contact with the rigid friction-pulley E, and through theconnections on the end of the shaft give motion to the mortising andgigging part of machine.

H is a lever, upon the end of which is secured the brake I, designed, bycontact with the face of the rigid pulley E, when applied, to arrest themotion of the shaft B. A latch-link,

J, secured to the lower end of the brake-lever H,may be hooked to thelever G, as shown, in which case both levers may be actuated simultaneously. By unhookingthislink-connection the levers may be actuatedindependently of each other, as occasion may require. I

I have not illustrated the parts of the boring-machine proper; but itbeing understood that the pulley D operates by belt-connection theboring apparatus, and the crank-connections at the end of the main shaftoperate the mortising and gigging devices, and that these devices aresubstantially as shown in the patent hereinbefore cited, the operationwill be suffi- 7o ciently understood.

What I claim as my invention is 1. The powerpulley O, friction-pulleyF,lever G, and connections, combined with the loose pulley l) andconnections with the boring mechanism, and with the shaft B, havingrigid friction-pulley E, as and for the purposes specified.

2. The power-pulleyO,friction-pulley F, pulleyD,and shaft B, havingrigid pulleyE, combined with the lever Gr, lever H, brake I, andlatch-Iink'J, as and for the purposes specified.
